Abstract
New type of fluoride ion catalyzed allylation agent (1a, 1b), allenylation agent (9, 10), and alkynylation agent (17) can be successfully utilized for various carbonyl substrates. The rate acceleration is ascribable to the shift of equilibrium to the chelate complexes with Bu4NF by the favorable chelation of bis (silyl) compounds toward the fluoride ion. The 19F NMR spectrum (ethyl trifluoroacetate as external standard) of a mixture of 1a and Bu4NF in ...
